Hoya 52mm 80A Color Conversion Hoya Multi-Coated (HMC) Glass Filter

The Hoya 52mm 80A Hoya Multi-Coated (HMC) Glass filter is blue. It is used to balance daylight film under artificial, tungsten or standard (household) incandescent lighting.

Let's say you're at a family gathering and you've brought your camera and want to take some photos of this once-a-year gathering. You have traditional daylight balanced film but find yourself in a room filled with table lamps. If left unfiltered, your photos will turn out yellowish. Under certain circumstances, perhaps a nice effect but not flattering in terms of skin tones or what our eyes are used to seeing or expecting. Enter the 80A filter!
